Returns the maximum number of pixels that the document can be scrolled horizontally.


xpix = window.scrollMaxX
  • xpix is the number of pixels.


// Scroll to most right of the page
var maxX = window.scrollMaxX;

window.scrollTo(maxX, 0);


Do not use this property to get the total document width, which is not equivalent to window.innerWidth + window.scrollMaxX, because window.innerWidth includes the width of any visible vertical scrollbar, thus the result would exceed the total document width by the width of any visible vertical scrollbar. Instead use document.body.scrollWidth. See also window.scrollMaxY.


DOM Level 0. Not part of any standard.
